It was cardiac arrest, not heart attack. Cardiac arrest has nothing to do with clots but involves a disruption in the electrical current of the heart. Clots result in a heart attack.
Calls to mind the prophetic conclusion of the Babylon Bee: "We don't know the cause, but it's definitely not the 'vaccine'". I'm so relieved (despite that I've never deliberately exposed myself to the potentially lethal "vaccine".) Cheers!
They share the same source - the mRNA 'spike' in the clot-shot causes inflammation in all the organs of the body over time. Including the heart.
